Biological data As with other members of the Panchaetothripinae, the species of this genus are all leaf-feeding. Distribution data Distributed across the Palaeotropics, from Africa to The Philippines, northern Australia and southern China. Nomenclatural data Panchaetothrips Bagnall, 1912: 258. Type species Panchaetothrips indicus Bagnall, 1912, by monotypy. There are seven species recognised in this genus, of which two are recorded from China: bifurcus Mirab-balou & Tong, 2016: 151. indicus Bagnall, 1912: 258. Relationship data Thripidae sub-family Panchaetothripinae: this group is represented widely around the world, particularly in tropical areas, and comprises about 40 genera. Panchaetothrips is one of seven genera from Africa that seem to form a single clade within the Panchaetothripinae (Mound et al., 2001). The species of Panchaetothrips are distinguished by the presence of sculptured ridges anterolaterally on the second abdominal tergite, and the elongate, parallel-sided tenth abdominal segment (Mound & Postle, 2004).

Due to the long history of regular interceptions of C. fasciatus in Australia, a survey for this thrips was undertaken around airports, seaports, public recreational parks and major agricul- tural areas in the states of Queensland, New South Wales, Victoria, South Australia and Western Australia to determine whether C. fasciatus has successfully invaded Australia. Host plants that are known to support populations of C. fasciatus, such as various annual and perennial agricultural crops, urban ornamentals and weeds along with native Australian ﬂora, were sampled for this thrips. A total of 4675 thrips specimens encompassing at least 76 species from a minimum of 47 genera, and three families were collected from at least 159 plant species in 67 families. Caliothrips striatopterus was collected in Queensland, but the target species, C. fasciatus, was not found anywhere. An undescribed genus of Thripidae, Panchaetothripinae, was collected from ornamental Grevillea (var.

Box 7144165186 (Received: 7 September 2015 ; Accepted: 7 November 2015 ) The genus Sericothrips Haliday is reported for the first time from Iran, based on the specimens collected on Lotus sp. and identified as S. bicornis (Karny). This is the third genus of subfamily Sericothripinae in Iran, and illustrations are provided to identify this species. The number of Thysanoptera genera now known from Iran is discussed, as well as the host associations of Iranian Sericothripinae. Key words: Iran, genus, new record, Urmia, thrips. INTRODUCTION Thirteen families of insect order Thysanoptera or thrips are recognized, including 5 known only from fossils (Mound, 2011a). Of the eight living families, the members of family Thripidae have the most close association with plants. In this family, four subfamilies (Dendrothripinae, Panchaetothripinae, Sericothripinae, Thripinae) are recognized. Within Thripinae, most species feed on leaves or pollen although Scolothrips Hinds species exclusively prey on tetranychid mites on various plant leaves (Mound, 2011b; Minaei & Abdolahi, 2015) and Frankliniella occidentalis (Pergande) , F schultzei (Trybom) and Thrips tabaci Lindeman also sometimes feed on mites despite being important pest species (Mound & Teulon, 1995; Wilson et al., 1996).

E-mail: [email protected] Abstract Heliothrips longisensibilis sp. n. is described from the tropical regions of southern China, Yunnan and Hainan, based on morphology and data from mitochondrial and nuclear genes. However, specimens that are identical in colour and structure are reported from northern Brazil, and this is presumably the area of origin of this new species. The area of origin within South America of the Greenhouse Thrips, Heliothrips haemorrhoidalis, is discussed and remains in doubt. An identification key to the four species of Heliothrips is provided. Key words: Heliothrips longisensibilis, new species, mitochondrial genes (COI), nuclear genes (ITS2+28S+EF-1α) Introduction The greenhouse thrips, Heliothrips haemorrhoidalis, is one of the most well-known species of Thysanoptera and is recorded widely around the world. Despite this, all three species currently included in the genus Heliothrips are presumed to be native to South America (ThripsWiki 2019).

In another genus, Bhattithrips, a new species B. borealis is described from northern Australia, and the four members of this Australian genus are distinguished in a key. A species described from Southeast Asia, Astrothrips aureolus, is established and probably native to northern Australia, where it damages the leaves of an Hymenocallis cultivar (Amaryllidaceae). Key words: Parthenothrips dracaenae, Bhattithrips, Astrothrips, new species, new genus Introduction The Panchaetothripinae is one of the four subfamilies recognised in the family Thripidae. This subfamily comprises the thrips with strongly reticulate cuticle on body and legs, and includes Heliothrips haemorrhoidalis, the ubiquitous Greenhouse Thrips (Mound et al., 2001). With the description of the new genus below, 39 panchaetothripine genera are now recognised worldwide, and of these 18 are known from Australia. Four of these genera involve immigrant species from other continents: Hercinothrips from Africa, Heliothrips and Selenothrips from South America, and Caliothrips with two species from Asia and Africa, plus a third recorded in Australia only from specimens taken in quarantine on oranges imported from western North America.

O’DONNELL1& LAURENCE A. MOUND2 1USDA, Systematic Entomology Laboratory, Beltsville, Md, USA. E-mail: [email protected] 2Australian National Insect Collection, CSIRO, Canberra, Australia. E-mail: [email protected] Abstract Heliothrips similis sp.n. is described as a close relative of the greenhouse thrips, Heliothrips haemorrhoidalis. This is the third species recognized here in the Neotropical genus Heliothrips. A pest species described from South Africa as Helio- thrips sylvanus is transferred to a new genus, Neoheliothrips gen.n., as Neoheliothrips sylvanus (Faure) comb.n. Key words: greenhouse thrips, Heliothrips, Neotropics, new species, new genus Introduction The greenhouse thrips, Heliothrips haemorrhoidalis, is one of the most ubiquitous members of the insect order Thysanoptera. It probably originated, as discussed below, in the southwestern part of the Amazon Basin, but is now known widely around the world, breeding on the leaves of a wide range of plants in many different families (Scott- Brown & Simmonds 2006).The species was first described in 1833 by Bouché as Thrips haemorrhoidalis, from specimens damaging leaves of plants in “warmen und kalten Häusen” presumably in Berlin. In 1836, and without any reference to this publication from Germany, the genus Heliothrips was erected by Haliday for a new species that he called adonidum, based on specimens collected in “hothouses” by Francis Walker, presumably in England.

Abstract: Interest in bioenergetic crops, such as the castor oil plant Ricinus communis (Euphorbiaceae), for production of biodiesel has increased in recent years. In this paper, phytophagous arthropods, their natural enemies and floral visitors associated with this plant in the world are reviewed. Despite its insecticidal properties, arthropods have been reported feeding on R. communis plants. The arthropod pests of R. communis damage all parts of the plant, including the seeds, where some toxic compounds are even more concentrated. In the scientific databases, we found reports of 193 arthropods associated to R. communis in different parts of the world. This information obtained in the scientific databases was concentrated in a database and analyzed according to the coevolutive hypothesis, which allows us to predict that the greatest wealth and abundance of phytogenic arthropods is found in the center of origin by R.

Thysanoptera Biodiversity in the Neotropics
Rev. Biol. Trop. 50(2): 477-484, 2002 www.ucr.ac.cr www.ots.ac.cr www.ots.duke.edu INVITED PAPER MINIREVIEW Thysanoptera biodiversity in the Neotropics Laurence A. Mound CSIRO Entomology, GPO Box 1700, Canberra ACT, Australia. e-mail: [email protected] Received 20-X-2001. Corrected 12-III-2002. Accepted 14-III-2002. Abstract: It is suggested that descriptive taxonomy of thrips must be integrated into biological studies if we are to understand patterns of evolutionary and ecological diversity. Collecting and describing new taxa is easy, but understanding their position in ecosystems and how they have contributed to the origin and maintenance of bio- logical diversity is more important yet more difficult. Many authors fail to appreciate that individual thrips species are commonly highly polymorphic, both within and between sexes, with the result that 20% of species names and 30% of generic names are currently placed into synonymy. The biological significance of such poly- morphism has been little studied, but the presence of large and small males in a species is presumed to indicate some form of male/male competition for resources; this is particularly common in fungus feeding species. Amongst phytophagous species, the recognition of the host plants on which thrips actually breed is a prerequi- site to understanding patterns of diversity, some thrips lineages being associated with particular groups of plants whereas others exploit a diverse range of plants. Attempts to understand the diversity of thrips, including the application of cladistic methods, are severely limited by the lack of studies on the biology of individual species, although thrips exhibit a wide range of interesting biological phenomena, including various levels of sociality, gall-induction, specific pollination associations, virus transmission, and ectoparasitism.
